WOLF CREEK, Ore. — Oregon State Police is continuing its investigation into a fatal crash on Interstate 5 Wednesday afternoon.

Troopers say around 1 p.m. a freightliner truck pulling a semi-trailer sideswiped a pickup and trailer parked on the side of the road. The pickup and trailer belonged to an employee of the Knife River Corporation who was working on a paving project. The pickup was stopped on the right shoulder with overhead caution lights and emergency flashers activated. The employee, 60-year-old Kathleen Roberta Wilson, of Trail, was outside of the pickup breaking down a portable sign next to the guardrail.

The semi-trailer sideswiped the pickup and caused part of the trailer to go over the top of the guardrail and struck Wilson.

Troopers say the driver of the semi-trailer, Jose Guadalupe Botello Sr., 58, of Salem, was unaware that someone was injured and continued until he stopped at a nearby gas station. Botello was contacted by an OSP trooper and went back to the scene.

After emergency responders arrived on scene, Wilson was pronounced deceased.
